Prolonged computer use is the number one cause of eyestrain among children and adults. Children can certainly limit the time spend in front of the computer. Adults who use the computer as part of their work will probably not be able to do this. However, by taking some simple precautions, they too can protect their eyes from problems like dryness and blurry vision.

If you stare at a computer monitor for prolonged periods, you may get dry eyes. This is usually a short-term problem. Also by taking a few precautions, you can avoid this from occurring.

Blink frequently

Blinking is essential to keep your eyes moist. When you work at a computer, you blink less often. This is what causes the dryness. Make sure that you blink your eyes frequently when you work on the computer. Also keep them closed for a few seconds or minutes every now and then.


Every ten minutes look at an object some ten feet away for about ten seconds. This simple act will make your eyes ready for when you get off from the computer.

Adjust brightness

Adjust the brightness of your computer monitor. If you reduce the brightness, reading may become easier. The screen should not be brighter than your surroundings. It should not be too dull either. You can, for example, use a brightness level of 0 and contrast level of about 80. But remember that these settings are different for different computers. So, choose settings that make your eyes the most comfortable.

Place the screen at a distance of 16-24 inches. Make sure that you can read comfortably. If you have to strain to read, it will only make your eyesight worse. Change the settings so that larger text will be displayed on the sites you visit.

Limit the use of computers

Reduce the time spent in front of the computer. Learn to type faster. You should also consider printing long pages for reading.

After working on your computer for long hours, you should lubricate your eyes with artificial tears. Alternatively, you can take a steamy shower. Don’t pour water into your eyes, as it will dilute the natural tears.

Stay hydrated. This will help the eyes to produce enough tears.

Take frequent breaks. Spending too much time in front of the computer may also cause fatigue.  Move about. This will also improve blood circulation.

Dry eyes may have a bloodshot appearance. This, however, doesn’t mean that you should use those ‘get the red out’ drops. They can make the condition chronic. All that you need to do is to get rid of the dryness. This will prevent the bloodshot appearance as well.
